Policy lapsed???

Took out a policy for my aunt a few years ago - I phone in this morning to check if the policy is still in order and I am told the policy lapsed in February 2018. I called in March/April 2018 and my policy had lapsed, but a consultant I spoke to said I should pay a certain amount of money and the policy would be reinstate. Policy number is ***9. Also, if the policy had lapsed why would I get an SMS every month saying the funds which I paid manually were received and allocated to a supposedly inactive policy. Please investigate this matter.
